Topic: Title: prop.comb.RR: R package for linear combination of proportions Authors:  Maria Alvarez Hernandez - University of Granada (Spain) [presenting]

Abstract: Inferences about a linear combination of several independent binomial proportions have aroused a great amount of interest, especially in applied research such as multicenter clinical trials, public-health surveys or epidemiology studies. The prop.comb.RR package is a software application for R to make inferences about a general linear combination of proportions and for classic cases as a proportion, the difference of proportions or the relative risk (particular instances of a linear combination). Inferences are solved not only from the perspective of the confidence interval, but also from the perspective of hypothesis tests. The implemented methods are optimal procedures selected in published literature and the well-known score method.
